BAG CHAIR POSITION
Bag chair is raised and lowered manually to adjust to bag length. A series of holes in the bag post accepts
a pin on the bottom of the chair assembly, resulting in a secure setting.
Pasted Bags:
Place a bag on the filling tube and smooth the body of the bag down. Unfold the
bottom of the bag to a horizontal position. Position the bag chair so that it touches the
bag.
Sewn Bags:
Place a bag on the filling tube and smooth the body of the bag down. For first setting,
position the bottom of the bag chair s1ot 1 " be 1ow the bottom of the bag.
Because of the wide variety of valve bags available, trial and error experimentation may be required to
obtain the optimum bag chair adjustment. Correct adjustment is best made with a filled bag.
Prior to removing the filled bag from the filling spout, verify that the weight of the bag is resting on the
bag chair and not hanging from the packer spout. The paper (or plastic) at the top of the bag should not
be under tension.
Incorrect bag chair adjustment is a common cause of off weight and bag size problems. Care should be
taken that the bag chair position is high enough to allow the bag to fill out properly at the end of the filling
cycle, especially in the upper portion of the bag. If the chair is not high enough, the bag capacity may be
greatly reduced.
CAUTION: Improper use of the bag chair can cause damage to the weigh beam. Do not
drop, stand or jump on the bag chair.
MOTOVIBRATOR BAG CHAIR SETTLER POSITION
On units featuring the motovibrator settler function, the settler can be run in different modes. They are:
Continuously through the entire fill cycle – In this mode in the PLC has a timer that can be adjusted as
when to start. This is to allow time for material to get into the bag before starting to settle .This is the
most common setup.
Settling during the Bulk Cycle only – In this mode the controller has to have bulk and dribble feature.
When the bulk set point (setpoint 1) is reached the settler will stop and drop down.
